Can lactic acid cause irritations?
Even though it is generally mild, the lactic acid can cause irritations when used excessively or at too high a concentration.
Can sensitive skin types use lactic acid?
The lactic acid is generally suitable for sensitive skin. However, it is recommended to start with a low concentration and monitor the skin's reaction to avoid any irritation.
Is lactic acid photosensitizing?
Lactic acid can indeed make the skin more sensitive to the sun. Therefore, it is recommended to use it in the evening and apply sun protection the following morning.
